“…It can be seen that for Mix 1 at the replacement level 30% flexural strength decreased than that of normal concrete. Variation in shape and rough texture may improve the bond strength and results in increase of flexural strength that also confirmed by the other authors [1] & [4]. Results from all the mixes are comparable with each other and we can say that up to25% replacement of sand can be done without having an adverse effect on the flexural strength.…”

“…They also suggested that UPV test represents porosity and density of hardened concrete, quarry dust with RHA behaved better than that of the normal concrete. Sreekrishnaperumal Thanga Ramesh et al, (2013) [4] showed that the furnace and welding slags have been utilized in the work by using it in the building materials as addition to concrete. WS and FS concretes showed better performance towards compressive strength.…”

Sustainability and Unavailability play an important role while we choose material for manufacturing of concrete. Nowadays, both Central and State Govt. have taken legal action on the extraction of sand from the river bed due to the bad impacts on the river like changes the shape, slope of the bed and also in the channel morphology. Due to the implementation of this type of law, legal sand quarries did not able to make balance with the rapid growth of the construction industry. That's why, to make profit and supply extra needs of sand to the concrete industry "Sand Mafias" involved into the illegal trades of the sand. To counteract these sorts of socioeconomic problems, we have to go for an alternative fine aggregate. Though it may not be possible to replace fully, we have to concentrate on the sand being replaced by the high percentage of alternative fine aggregate. Stone dust is a byproduct from rock crusher and it can be recycled by using it in the concrete and maintained the sustainability. As stone dust has acceptable properties of fine aggregate sand with regard to shape and texture, it can be thought of as an alternate fine aggregate but research is needed on the extent of sand replacement by stone dust. The present study is done keeping in mind the use of stone dust as high as possible. That's why two Design Mix have been designed M20 and M25. For M20 grade of concrete sand has been replaced by stone dust 25%, 30% and 35% by volume and the basic strength properties of concrete have been investigated for the above replacements like compressive strength, flexural strength, split tensile strength etc. In case of M25 grade of concrete 30%, 40% and 50% replacement of sand have been done and variation cement content and water-cement ratio has been done by comparing the target mean strength of M25 grade of concrete.

“…Similar studies have been conducted on the utilization of steel slag as aggregate is advantages when compared with normal aggregate mixes [5,6,7]. On the other hand, experimental researches indicated that the results steel slag aggregate concrete achieved the strength performance of EAFSS concretes is similar to that of a more traditional concrete, with a higher compressive strength and a slightly less flexural strength, [8,9,10]. This research aims to investigate the effect of using the locally produced electric arc furnace steel slag (EAFSS) in Egypt as a replacement of the natural coarse or fine aggregate on the properties of normal, high and ultra-high strength concrete.…”

Steel slag is produced as by-product during the oxidation of steel pellets in an electric arc furnace. This by-product can be broken down to smaller sizes to be used as aggregates in asphalt and concrete. In the current research, locally produced steel slag in Egypt was used as a replacement of the natural aggregate for producing high strength concrete. Four groups consisted of twenty-four normal, high and ultra-high strength concrete mixtures with replacement percentages 0%, 33.33%, 66.67% and 100% by weight of the coarse aggregate with two cement contents (450 kg/m 3 and 600 kg/m 3 ) and three silica fume percentages (0%, 10% and 20%) were investigated. In addition, other three groups consists of six concrete mixes of cement contents 350 kg/m 3 and 450 kg/m 3 were cast to study the possibility of using the fine electric arc furnace steel slag particles as a replacement of the used natural fine aggregate in the concrete mixtures . The effect of the studied key parameters which are the replacement ratio of the used electric arc furnace steel slag (EAFSS), the cement content and the silica fume percentage on the volume weight, compressive strength, flexural strength, indirect tensile strength, static of elasticity modulus and Permeability coefficient were studied. The results indicated that the highest concrete strength was obtained for the mixtures possessed a percentage of 66.67% steel slag aggregates as a replacement of the coarse aggregate. Moreover, the replacement of the natural fine aggregate by the fine steel slag as well as the EAFSS coarse aggregate produced a high strength pervious porous concrete.

According to the European Cement Association, CEMBUREAU, in 2015, the global cement production was 4.6 billion tons. Traditional cement production emits approximately 1 ton of CO 2 per ton of cement, which represents almost 80% of the total CO 2 emissions of concrete and approximately 6% of the world's emissions. Among supplementary cementitious materials, the use of agro-waste ash emerges due to its reduced CO 2 emissions, chloride diffusion, and materials cost, in addition to its greater compressive strength. In Colombia, the disposal of agro-wastes, such as tobacco waste, is an environmental and economic concern. In this study, ash obtained from tobacco waste (TWA) was studied as a sustainable partial replacement for cement in hydraulic concrete. The TWA was reduced to a particle size of less than 75 μm and was characterized by X-ray florescence. A central composite design was used to study the influence of the ash replacement percentage of cement and the water/binder (w/b) ratio on the compressive strength at 28 days. The results show that it is possible to replace 10% of the cement with TWA using a 0.5 w/b ratio and obtain a 51% higher compressive strength than the control mixture at 28 days. Moreover, the experimental results demonstrated an improvement of 86% in the 7-day compressive strength when TWA was used.
